A 1.56kg seagull dives through the air and gains 4495 of energy.What is the birds speed?
What are your units of energy?
Use the kinetic energy formula and solve for V
To calculate the speed of the seagull, we need to use the equation for kinetic energy:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
Given:
Mass (m) = 1.56 kg
Energy gained (KE) = 4495 J
We can rearrange the equation to solve for velocity:
velocity^2 = (2 * KE) / mass
Now, let's plug in the values:
velocity^2 = (2 * 4495 J) / 1.56 kg
Simplifying:
velocity^2 = 5743.59 m^2/s^2
To find the velocity, we need to take the square root of both sides:
velocity ≈ sqrt(5743.59) ≈ 75.82 m/s
Therefore, the seagull's speed is approximately 75.82 m/s.
